LG Multi F LGRED R32 Heat Pump | 4 Indoor Units - 1 Compressor 30000 BTU

A multi-zone solution designed for demanding Quebec residences and buildings

At AirGreen , we have been installing HVAC systems for over 15 years in Montreal , Laval , Longueuil , on the North Shore , the South Shore , and in the Montérégie region . The LG Multi F LGRED R32 – 30,000 BTU, quad-zone heat pump is one of the solutions we recommend when the needs are clear: multiple independent zones, a single outdoor compressor, stable performance in cold climates, and clean integration into existing buildings.

This model is aimed at homeowners who want to precisely control the temperature of up to four separate spaces , without multiplying outdoor units, while maintaining energy efficiency consistent with Quebec winters.

System architecture: a single outdoor unit, four real zones

The LGRED R32 Multi F configuration is based on a KUMXA301A outdoor compressor capable of powering up to 4 compatible wall-mounted indoor units (e.g., KNUAB, KNUAK, KNMAB series, depending on the chosen capacities). This architecture offers several concrete advantages:

• Reduction of external obstructions (balcony, courtyard, roof)

• Independent management of zones : bedrooms, living room, office, secondary accommodation

• Sizing flexibility : mix of 9,000, 12,000 or 18,000 BTU depending on the room

• A more discreet interior aesthetic , without compromising on comfort

In our projects in Outremont , Boucherville and Laval-des-Rapides , this type of configuration is often chosen for multi-storey houses, duplexes or condominiums where outdoor space is limited.

Heating performance: stability down to -25°C

One of the key features of the LG Multi F LGRED R32 is its ability to maintain reliable heating performance in cold climates. The variable-speed compressor and electronic management of the R-32 refrigerant enable:

• A nominal cooling capacity of 30,000 BTU

• Heating capacity maintained down to -25°C

• A gradual modulation, avoiding abrupt on/off cycles

During our installations on the North Shore , we observe that this type of system is particularly appreciated for its thermal stability , especially in the mid-seasons where temperature variations are frequent.

R-32 refrigerant: efficiency and environmental compliance

The choice of R-32 gas is not insignificant. Compared to older refrigerants:

• It offers better thermodynamic efficiency

• It requires a lower total load

• Its global warming potential (GWP) is reduced

In a context where environmental standards are evolving rapidly in Quebec and Canada, this point is important for owners who want a sustainable system that meets current and future requirements.

Acoustic comfort and intelligent control

Another often underestimated aspect concerns noise levels . The outdoor compressor has a sound pressure level of around 55 dB(A) , which remains reasonable for a multi-zone system of this capacity. Indoors, depending on the units chosen, levels can drop below 30 dB(A) in low mode.

Regarding control:

• Built-in Wi-Fi via the LG ecosystem

• Individual remote controls per zone

• Precise control of shutters (automatic horizontal and vertical)

• Timetable adapted to the actual habits of the occupants

In several residences in Longueuil and Plateau-Mont-Royal , this granular control has made it possible to reduce actual consumption , simply by avoiding unnecessarily heating or cooling certain areas.

Installation: Why AirGreen's expertise makes the difference

A multi-zone system is never a standard installation. The errors we most often correct on existing installations include:

• Poor capacity ratio between indoor units and compressor

• Unbalanced pipe lengths

• Inadequate drainage leading to noise or condensation

• Electrical undersizing

At AirGreen , each project begins with a real thermal analysis , then:

• Precise selection of indoor units

• Strict adherence to permissible lengths and elevation changes

• Prolonged and controlled vacuum sealing

• Complete check of heating and air conditioning

It is this level of rigor that explains why this model is regularly installed in our high-end residential projects, but also in multi-unit dwellings requiring reliability and consistency.

LogisVert subsidy and long-term value

At the time of writing, this system is eligible for the provincial LogisVert grant , with an indicative amount of up to $2,388 , depending on the final configuration and applicable criteria.

Beyond the subsidy, the real value is measured by:

• Compressor durability

• Reducing corrective interventions

• Stable comfort, even in periods of intense cold

Who is the LG Multi F LGRED R32 really aimed at?

This system is particularly relevant if:

• You want 4 independent zones with a single compressor

• Outdoor space is limited

• Are you looking for a reliable solution for Quebec's climate?

• You want a clean, durable and well-balanced installation

It is less suitable if:

• Only one area needs to be air-conditioned.

• The thermal loads are very low

• A centralized, ducted solution is already in place and optimized.

Why choose AirGreen for this system?

Choosing AirGreen means:

• Certified refrigeration technicians , experienced in multi-zone systems

• Clear prices , confirmed before work begins

• $5 million liability insurance

• Real-time follow-up after installation

We never install a multi-zone system unless we are convinced that it is technically justified for the building in question.
